The AD9213 is a single 12-bit, 10.25 GSPS, RF analog-to-digital converter (ADC) with a 6.5 GHz input bandwidth. The AD9213 has been optimized to support high dynamic range frequency and time domain applications requiring wide instantaneous bandwidth and low code error rates (CER). The AD9213 features a 16-lane JESD204B interface to support its maximum bandwidth capability.

The AD9213 achieves industry leading dynamic range and linearity performance while consuming only 5 W. Based on an interleaved pipeline architecture, the AD9213 features a proprietary calibration and randomization technique that suppresses interleaving spurious artifacts into its noise floor. The excellent linearity performance of the AD9213 is preserved by a combination..
